Johannes Berg says:

====================
Three fixes:
 * for certificate C file generation, don't use hexdump as it's
   not always installed by default, use pure posix instead (od/sed)
 * for certificate C file generation, don't write the file if
   anything fails, so the build abort will not cause a bad build
   upon a second attempt
 * fix locking in ieee80211_sta_tear_down_BA_sessions() which had
   been causing lots of locking warnings
